Question:

As-salamu alaykum wa rahmatullahi wa barakatuh,

Is it permissible to recite the Qur'an while donating blood if I have ablution (wudu)?

Does donating blood invalidate the ablution?

Answer:

Wa alaykum as-salam wa rahmatullahi wa barakatuh,

As long as you have ablution, it is permissible to recite the Qur'an while donating blood. Also, even if you do not have ablution (but are in a state of purity), you can recite the Qur'an from memory or read a book of exegesis (tafsir).

According to the scholars, it is most likely that donating blood does not invalidate the ablution, but it is better and more preferable to renew your ablution afterward.

And Allah knows best.
